Add folder support to Azure blob storage commands

Browse Source 
This change adds a --folder parameter to both 'vpk upload az' and 'vpk download az' commands, allowing users to organize releases in subdirectories within their Azure blob containers.

Key changes:
- Added Folder property to AzureUploadOptions and AzureDownloadOptions
- Modified AzureRepository to prepend folder paths to all blob operations
- Updated upload, download, and delete operations to work with folder paths
- Retention policy (--keepMaxReleases) correctly handles files in folders
- Release index and legacy release files are stored in the specified folder

This enables multiple applications or environments to share a single Azure container by using folders as isolated namespaces. For example:
- vpk upload az --folder "releases/v1" ...
- vpk download az --folder "releases/v1" ...

The implementation is backward compatible - existing deployments without folders continue to work as before.
